Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a toilet bowl with a seat switch that is activated when a toilet user sits on the toilet seat.

(Prior art) Conventionally, human body private parts cleaning devices have many electric parts driven by electricity, such as a pump for squirting cleansing water and a heater for drying after cleaning, in a housing installed in the toilet bowl body. has been done. In driving this electric component, the drive preparation signal detects that a weight is applied to the toilet seat on which the toilet user is sitting.
The signal from the seat switch is used.

This seated switch is, for example,
According to 140280, a microswitch that outputs an electric signal, a dog that operates the actuator of this microswitch, and a dog that holds this dog,
It consists of a movable lever that moves up and down in an elongated hole provided in the housing by the same amount as the amount of movement of the toilet seat.

(Problems to be Solved by the Invention) Therefore, most of the elongated holes communicate between the inside and outside of the housing. This communication allows humid air, water droplets, dust, etc. to enter the outside and inside of this housing. This humid air, water droplets, etc. cause the insulation of electrical components inside the housing to deteriorate and metal components to rust.

Therefore, the present invention prevents air and water droplets from entering from the outside of the housing to the inside.
The object of the present invention is to provide a toilet bowl with a seat switch that does not cause this deterioration of insulation.

[Structure of the invention]

(Means for solving the problem) The toilet with a seat switch of the present invention has a toilet main body,
A housing provided at the rear of the toilet main body, a toilet seat, a shaft device provided between the housing and the toilet seat to pivotably support the toilet seat relative to the housing, and the toilet seat relative to the housing. In a toilet bowl with a seat switch that is operated by a relative motion of A second plate that pivots the toilet seat.
A shaft member consisting of a shaft portion and a coupling portion fixed to at least the first shaft portion and connecting the first shaft portion and the second shaft portion, and a direction in which the second shaft portion is swung upward. and a biasing member that biases the first shaft portion, and the seating switch is characterized in that the switch is operated by rotation of the first shaft portion of the shaft device.

That is, this toilet with a seat switch is composed of a toilet main body, a housing, a toilet seat, a shaft device comprising a shaft member and a biasing member, and a seat switch operated by rotation of the first shaft portion.

The toilet main body and the toilet seat are used as a so-called Western-style toilet, and their shape, dimensions, etc. are not particularly limited.

Further, the housing usually houses a pump device, a drying device, etc., as well as part or all of a shaft device, which will be described later, and a seating switch.

The shaft member includes a first shaft portion which is rotatably held in the housing, a second shaft portion which is parallel to the first shaft portion and pivotally supports the toilet seat, and a second shaft portion which is fixed to at least the first shaft portion. , is a member consisting of a connecting portion that connects this first shaft portion and this second shaft portion. The first shaft portion and the housing are rotatably held by either having a bearing portion. This first shaft portion must have a switch actuating member for actuating a seat switch, which will be described later. This switch operating member is a member that turns on or off the seat switch depending on the rotation angle of the first shaft portion. As the switch operating member, for example, when a micro switch, reed switch, or sensitive coil is used as the seat switch, a cam plate having a predetermined development curve or development curve can be used; If a sensitive photoelectric element is used, a member with an element such as a light emitting diode can be used.

This second shaft portion is a member that pivotally supports the toilet seat so that its positional relationship with the toilet bowl can be functionally adjusted depending on when the toilet seat is used or not. Normally, the second shaft portion and the toilet seat are held together such that one is a shaft and the other is a bearing.

The connecting part is below the toilet seat user (ground).
This is a member that connects the first shaft portion and the second shaft portion so that when a directional load is applied, the first shaft of the first shaft member is rotated by the acting force from the second shaft member.
In other words, the coupling portion is a member that connects so that the amount of linear change acting on the second shaft portion is transmitted to the first shaft member as the amount of rotational change. Therefore, depending on the structure and shape of this joint, the amount of change in this straight line can be converted into any amount of rotational change.

The biasing member is a member that biases the first shaft portion in one rotational direction so as to swing the second shaft portion upward. As described above, the second shaft part and the toilet seat pivotally supported by the second shaft part swing in the vertical direction according to the rotational direction of the first shaft part. Therefore, from a functional point of view, the biasing member is a member that applies a rotational force to the first shaft of the first shaft portion so that the toilet seat can swing to its upper end at its initial position when the toilet seat is not in use. It is. As this urging member, for example, a spring or a magnetic pole having magnetic force can be used.

The seat switch is a switch that is operated by rotating the first shaft portion of the shaft device. This seat switch is a member that outputs an open/close electric signal using a switch operating member included in the first shaft portion described above. If possible, it is desirable that the current breaking capacity of this seat switch is greater than the total current used by the control system of this toilet with a seat switch;
It may be one that has a small withstand voltage capacity and simply outputs an open/close signal. As this seat switch, in addition to the ones exemplified above, most of the known switches can be used if the actuator is devised.

(Function) The toilet body holds the housing. The housing holds part or all of the shaft assembly and the seat switch. The first shaft portion of this shaft member is rotatably held by the housing. The connecting portion connects the first shaft portion and the second shaft portion that pivotally supports the toilet seat. on the other hand,
The biasing member is held by the shaft device so as to bias the first shaft portion in one rotational direction. Further, the seat switch is held in the housing so as to output an open/close signal by rotation of the first shaft portion. When a downward (ground) direction load is applied to the toilet seat, the first shaft section obtains a rotational force from this load via the second shaft section connection section and rotates. The seating switch is actuated by this rotation of the first shaft portion, and this seating switch outputs an open or close electrical signal. When the magnitude of this load becomes smaller than a predetermined value, the first shaft starts to rotate in the opposite direction to the current rotation by the biasing member, and when the rotation angle in the opposite direction becomes larger than a predetermined value, the seating switch receives the signal. Invert and output.

(Example) Hereinafter, the toilet bowl with a seat switch of the present invention will be described in detail based on a specific example.
